League of Millions: Inside the video game phenomenon that's selling out global arenas and earning stars up to $1 million

Far more than an internet video game, "League of Legends" is a cultural phenomenon, a pastime that is deeply ingrained in the lives and lifestyle of millions of fans worldwide. It appeals across cultures and demographics, inspiring a passion and sense of community rarely matched in modern culture.

Twenty-seven million people play it every day. At peak hours, more than 7 million people are playing concurrently.

Not only do people play it themselves, they love to watch others play — including the top pro "League of Legends" (LoL) teams, which span 4 continents and fill coliseums with fans.

BI Films presents Part 1 of its documentary series, "League of Millions," in which we meet the five young pros who make up Team Liquid, one of the leading North American LoL teams, in their quest to win the 2015 championship.
